Challenge A California refinery had a need to load gasoline, ethanol, and other high vapor pressure materials (classified as MVR products) onto barges. MVR products are required to have vapor control on them during transfer onto the vessel. The loading terminal is not equipped with any form of vapor recovery device on the dock. Without […]

Midwest Refinery Turnaround Services
A Midwest refinery contracted Envent to provide degassing and vapor control services. The refinery planned a major turnaround and had multiple critical-path process units that needed industrial degassing and industrial vapor control services for safe entry into process vessels.
Freeport, Texas, Out of Service Storage Tank Contaminated Water Treatment
A facility on the Gulf Coast had an out of service tank that once contained Pyrolysis Gasoline (Pygas), but had recently been used to store various waste streams and contaminated water.
Fort Worth, Texas, Mobile Water Treatment
A tank farm had collected over 600,000 gallons of storm water runoff. The storm water needed to be treated for total suspended solids, oil and grease, benzene, toluene, ethylene and xylene. The treated water would be discharged directly into Fort Worth’s sewer system.
Southern California Construction Site, Dewatering Operations
A general contractor was tasked with making major renovations to a utility company’s electrical transmission infrastructure. Construction dewatering was a major concern for the general contractor because the excavations were as close as 500’ from the ocean.
Power Station, Groundwater Removal for Conduit Boring
A construction company in San Diego needed to bore a hole under railroad tracks for a utility company to run wire underground, 15 ft below grade. The site location was a marine terminal, so Envent was contracted to dewater the area for digging and to treat the subsequent contaminated water. Savings of $24,000 and the successful discharge of 250,000 gallons of clean water.
